“What I can say though is what we have done with the game this time that I think a little bit different is… They’ve built an entire upgrade system into the game. So for example, right now you can see that Link has his traditional shield, but he actually will get a lot of diferent shields in the game. He will start off with a very basic one, and then as you fight enemies, you will recover these kind of treasures or artifacts that you can then use as resources to upgrade your items. And you can do that with your shield, you can do that with the beetle, and some of the other items that you have where you’re able to kind of combine your collection of rupees and your collection of resources and improve the items that you have.”
